“…Almost half of the injuries occur secondarily to acute or chronic trauma, mainly related to the type of occupation (10,11) . Ganglion cysts are the second most common cause; but, in these cases, the isolated compression of the deep motor branch alone is uncommon, particularly in those that present fast evolution, severe and progressive nature of the compression signs and symptoms (12) . The conduct indicated in patients with fractures, cysts or expansive processes is surgery.…”

Papers correlating clinical and electrophysiological findings relating to ulnar nerve lesions in the wrist are uncommon in the literature, if compared with elbow injuries. We present the case of a patient with atrophy of the intrinsic musculature of the hand, secondary to injury only of the motor branch of the ulnar nerve, which is located in Guyon's canal close to the hamate hook. We review the anatomical, clinical and neuThis article is available online in Portuguese and English at the websites: www.rbo.org.br and www.scielo.br/rbort rophysiological aspects of distal ulnar nerve injuries and we emphasize the importance of multidisciplinary approaches. Specifically in relation to the mechanism of injury of this patient (tug-of-war), we did not find any similar cases in the literature. We issue an alert regarding the risks during military physical training.

“…Ulnar nerve entrapment at the wrist is a rare condition as it is only 5% as high as the incidence of ulnar nerve entrapment at the elbow.

The floor of canal is formed by the transverse carpal ligament and roof by the volar carpal ligament.…”

Ulnar nerve compression at guyon's canal is rare and very few cases have been reported in literature. It can be missed due to its rarity. Symptoms vary from pain and paresthesia to wasting and significant loss of muscle strength, with significant deformities of the hand. The diagnosis is made by detailed history and examination, electromyography, nerve conduction velocity test, ultrasound and magnetic resonance imaging. Early decompression of nerve is treatment of choice. Here we are presenting a case of compression of ulnar nerve in guyon's canal due to ganglionic cyst.

“…This is likely due to the limited existing studies, which essentially consists of reports of a small number of cases or reviews of individual case reports. The most common reported causes are ganglion cyst compression and chronic trauma (occupational neuritis, repetitive trauma neuropathies) [3][4][5][6][8][9][10][11]. Compression caused by ganglia can be further subdivided.…”

Ulnar Neuropathy at the Wrist

A case of ulnar nerve compression at the wrist within Guyon's canal is reported. The clinical presentation initially appeared consistent with an ulnar nerve entrapment at the elbow. The true diagnosis of an ulnar sensorimotor nerve lesion occurring within the canal of Guyon was made electrophysiologically. Magnetic resonance imaging demonstrated compression of the nerve within the canal by a ganglionic cyst, which was confirmed by surgical intervention. Ulnar nerve entrapment at the wrist is uncommon and difficult to diagnose; therefore, it is important to understand the nerve's anatomical course and distribution to allow for accurate diagnosis by clinical and electrodiagnostic evaluations. Electrodiagnosis is an important tool in identifying ulnar nerve lesions at the wrist while excluding other disorders in the differential and recognizing coexisting pathology.
